Excess-Enthalpies of (Toluene Plus Methanol or Heptane or Methylcyclohexane) and of (Heptane Plus Methylcyclohexane) at the Temperatures 255.4 K and 310.9 K and the Pressure 13.8 MPa
Excess molar enthalpies H-m(E), measured by isothermal flow calorimetry, are reported for {xCH(3)OH + (1 - x)C6H5CH3}, {xC(6)H(5)CH(3) + (1 - x)CH3(CH2)(5)CH3}, {xC(6)H(5)CH(3) + (1 - x) c-CH(CH3)(CH2)(5)}, and {xCH(3)(CH2)(5)CH3 + (1 - x)c-CH(CH3)(CH2)(5)} at the temperatures 255.4 K and 310.9 K and at the pressure 13.8 MPa. The H-m(E) values were fitted with a polynomial equation. The H-m(E) results are explained in terms of chemical, physical, and structural effects.
